Ngc/Pcgs customizable case bumper

This 3D-printable protective bumper case is custom-designed for Numismatic Guaranty Company (NGC) coin slabs, with inner dimensions of approximately 60.6 mm x 85.9 mm x 9.5 mm to accommodate standard NGC slabs with a slight tolerance for easy insertion. Crafted for printing in flexible materials like TPU, the case features 3 mm thick side walls to shield the slab's edges from impacts and scratches. Thin 1.2 mm lips with a 4 mm overhang on both the front and back securely grip the slab while leaving large open windows for unobstructed viewing of the coin and label. The minimalist design ensures a snug fit, easy snap-on installation, and reliable protection without compromising visibility. Perfect for collectors looking to safeguard their graded coins during handling, storage, or display. Fully customizable in OpenSCAD for adjustments to fit specific needs or printing preferences.
